State the Physical Properties of Non-metals.

1.	State the Physical Properties of Non-metals.
Answer» Physical Properties of Non-metals Physical State - Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (iodine, carbon, sulphur). These have no metallic lustre, (except iodine) and do not reflect light. (Except carbon in the form of diamond). Nature - Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets. Except- diamond is the hardest substance known. Conduction - They are poor conductors of heat and electricity. (Except graphite conducts heat, both graphite & gas carbon conduct electricity.) Electronegative Character - Non-metals have a tendency to gain or share electrons with other atoms. They are electronegative in character. Reactivity - They generally form acidic or neutral oxides with oxygen. Melting and Boiling Points – Non-metals have low melting and boiling points.
